Hi,
I created new board specific files gd_xxxx similar with malta_xxxx and I
am trying to configure Linux interrupts in gd-int.c.
My board has no external interrupt controller like Malta has, it has no
PCI, I use Vectored interrupt mode and a mux routes the external
interrupts to the MIPS h/w interrupts.
Wthat is the meaning of the following switches and how to set them:
cpu_has_divec
cpu_has_vce
cpu_has_llsc
cpu_has_counter
cpu_has_vint
What is the difference between:
setup_irq()
set_irq_handler()
set_vi_handler()
Can you point me to document regarding interrupts implementation in MIPS
Linux?
Other than the Linux Kernel source code, make sure you have a copy of:
MD00090-2B-MIPS32PRA-AFP, the "MIPS32® Architecture for Programmers
Volume III: The MIPS32® Privileged Resource Architecture"
It can be downloaded from mips.com
